简要总结
Liver transplantation in France represents a currently significant transplantation activity with a steady increase in the number of transplanted patients, with 1,294 liver transplants according to the Biomedicine Agency in 2022 compared to 806 liver transplants in 2000. 4% of these transplanted patients, or 54, underwent combined liver-kidney transplantation in 2022.
The indication for combined transplantation fits within several scenarios: patients indicated for liver transplantation with severe renal insufficiency as a comorbidity, which worsens the prognosis in the case of liver transplantation alone; patients with renal insufficiency indicated for kidney transplantation with decompensated liver disease as a comorbidity; and diseases affecting both organs in a combined and severe manner.
However, some American studies have highlighted the significant prevalence of kidney transplant failure during simultaneous liver-kidney transplantation, estimated at around 20% at 3 months post-transplant. This failure of renal function recovery after the double transplant is defined by the need for dialysis or the occurrence of death. This represents a major issue concerning the mortality and morbidity of patients who have undergone simultaneous liver-kidney transplantation.
The aim of this study is to identify the risk factors for failure of renal function recovery after combined liver-kidney transplantation, thus indicating the futility of the kidney transplant in this context of double transplantation.
The outcomes will be multiple. On one hand, we will identify the population most suitable to benefit from this intervention, which will improve recommendations on access to simultaneous liver-kidney transplantation. On the other hand, we will develop an optimized strategy for the use of available grafts, in order to better address the current organ shortage and the increasing number of patients waiting for transplants.

结局指标
主要结局
Renal futility, defined as the need for dialysis (intermittent or continuous) or occurrence of death at 3 months after simultaneous liver-kidney transplantation
时间窗: The outcome is collected at 3 months following the simultaneous liver-kidney transplantation.
The primary outcome is met if the patient undergoes dialysis (continuous or intermittent) or is dead at 3 months after simultaneous liver-kidney transplantation. The outcome is not met if the patient required dialysis during the early stages of their transplant but no longer needs it and is not undergoing dialysis at 3 months. The criterion is not met if the patient dies after the 3-month period following simultaneous liver-kidney transplantation. This outcome is collected from electronic medical records by designated and authorized personnel. These records are stored within the hospital departments where patients are being monitored.
